Abstract
Unbiased samples of ground states were generated for the short-range Ising spin glass with J(ij) = +/-1, in three dimensions. Clustering the ground st ates revealed their hierarchical structure, which is explained by correlate d spin domains, serving as cores for macroscopic zero energy "excitations."
